Answer 1

Declare a variable UpdatedRecords of TABLE OF Deposit%ROWTYPE and add RETURNING BULK COLLECT -clause to your UPDATE statement.

UPDATE ... RETURNING <all fields> BULK COLLECT INTO UpdatedRecords;

After the execution UpdatedRecords variable will be a collection of updated records as they were looking before changes. Scan it with LOOP and print what ever you want.

You can also reduce a number of fields collected after the executeion, just change RETURNING clause and give the proper declaration for UpdatedRecords variable.

Refer to Oracle documentation http://docs.oracle.com/database/121/LNPLS/returninginto_clause.htm#LNPLS01354 for RETUNING clause.
